<p> The purpose of this research is to clarify the relationships between multi-functionality of urban agriculture （MFUA） as city amenities and creative classes （CCs） for Tokyo and Shanghai, the two global cities in Asia. Specifically, based on existing studies on creative classes （CC）, multi-functionality of agriculture （MFA）, social capital （SC） and social business （SB）, we constructed a model showing that these factors contribute to the sustainability of global cities, and verified the model through the covariance structure model （SEM） analysis using the authors' original questionnaire survey targeting the residents in the two cities. In addition to creative classes based on traditional creative occupations, we also focused on CC based on Creative Thinking, their orientation toward multi-functionality of agriculture and the relationships with social capital, and how they engage in social business. </p><p> The following results were obtained from our analysis. First, the creative classes （both creative occupation and creative thinking） in Tokyo and Shanghai prefer multi-functionality of agriculture than non-CC （Hypothesis 1）, such tendency is more strongly evident in Tokyo. Secondly, people who are creative thinking in both cities have a high level of social capital （Hypothesis 2）, and strong willingness to participate in social businesses （Hypothesis 3）. Based on the analytical results, we draw the implication that urban policies should facilitate CCs （both creative occupation and creative thinking） to actively participate in social businesses by making full use of the multi-functionality of agriculture to solve social problems in global cities.</p><p>JEL Classification:R11</p>
